THE CANADIAN HORTICULTURIST. 



Fig. 2247. Showfhg the condition of one of the trees sprayed on one side at the time of picking the 

 fruit. The leaves have been cut away with the pruning shears to enable the photograph to show the 

 fruit upon the sprayed half (right side) of the tree, and the absence of fruit upon the unsprayed half 

 (left side). The sprayed half matured 284.8 pounds of the finest peaches ; the unsprayed half matured 

 only 13.3 pounds. Over 1,100 peaches were thinned from the sprayed half of this tree to enable the 

 limbs to bear the crop, while the unsprayed half was unthinned except by curl. 



was boiled in an iron kettle three hours and 

 the sulphur thoroug-hly incorporated. It 

 was applied to the trees while yet very hot 

 and covered them completely. The spray- 

 ing was finished in a lig-ht rain, which in- 

 creased to a heavy rain and continued all 

 nig-ht and the next day. This was followed 

 during the rest of the month, by alternate 

 fine and rainy weather, making altogether 

 the wettest May I ever knew. It is gener- 

 ally believed that the success of this treat- 

 ment in California is due to the absence of 

 rainfall and that, in any case, a couple of 

 weeks of dry weather, immediately following 

 the application, is indispensable to its suc- 

 cess. This work was closely watched by 

 the neighbors all the way through and the 

 result carefully observed, and the consensus 

 of opinion is that there was an entire 

 absence of leaf curl, the foliage was plenti- 



ful and well developed, the wood brighter 

 and cleaner, and the fruit larger, higher 

 colored and more plentiful than in adjoining 

 trees. 



In this experiment, as in the others, the 

 treated row reached across the orchard and 

 all varieties present were included. 



Encouraging Results. — The very promising 

 indications from this St. Catharines work 

 led to an extended enquiry as to what use 

 had been made of this remedy. The replies 

 are disappointing and show distinctly that 

 the favorite remedy which, in many parts of 

 California has superseded all others, has not 

 received even so much as a fair trial in the 

 East. It was tried experimentally last 

 spring by Dr. Howard, Chief Entomologist 

 at Washington, D. C, and by the growers 

 in Burlington County, New Jersey, and they 

 report unexpectedly good results.
